摘要

"External device independent supply of voltage stabilized for feeding various internal circuits of a television set.This patent is an external device to feed the internal circuitry of a television set, equipped with a set of independent and mutually isolated stabilized sources.Provided with protection against short and with diodes in series on the output to avoid a possible return, allowing a rapid diagnosis, accurate and safe of the defects of the television.To avoid the occurrence of damage in components in good condition.In general, the novelty consists of an external device powered by the electrical network and consists of a square box or other suitable fomato,Which houses a circuit controlled by a switch (1) and a processor (2) with five exits (3), (4), (5), (6) and (7), respectively and the tension of 5, 12, 20,60 and 110 volts AC, each of these outputs being connected to a respective circuit board (8), (9), (10), (11) and (12), which is a steady source independent,Isolated from the others and provided with internal protection against short circuits and with a diode in series on the output, providing direct current voltages respectively at 5, 12, 25,75 and 115 volts DC, each of these sources being interconnected to a corresponding protection against short circuit.Which is triggered in case there is short circuit on the board or component of the television that this source is connected.Each source being connected to a pair of wires through the front panel (13) and has a respective pair of claw type connectors.The source of lower voltage (5 V) feeding a light bulb or LED driver (14) indicator of the operation of the device, while the others are on-off switches
